Bringing UFH temperature back up after floor tiling

[Hannah82w]

We recently had our main living area floor tiled, having turned the underfloor heating pretty much off before tiling commenced (the screed was poured 10 months ago and UFH heating commissioned 6 months ago, was on and gradually increasing temp over about 6 weeks until the warmer weather arrived and then back on again recently bringing the flow rate temp up to a max 35 degrees). During and since tiling, the flow rate temperature in the actual UFH pipes seems to have held at about 12 degrees and the ambient air temp around 15 degrees.

 

Advice online suggests keeping the temperature at about 15 degrees during and after tiling (I assume this is ambient air temp, which it has been) and not bringing the heating back on/up for 7-10 days (we're giving it at least 14 days), but when you do the advice talks about bringing the temp up to no more than 27 degrees and to do so in 5 degree increments. Presumably this is also the ambient air temp, so can I also assume that you would bring the flow rate temperature in the actual UFH pipes up at about the same rate?

The UFH should be switched off during tiling and left off for a week after grouting Then crank it back up to required temperature
